Mass percentages of the the elements in the compound is the only additional information needed to calculate the empirical formula of a compound if the masses of each element of the compound are provided.

<h3>What is Empirical Formula ? </h3>

The Empirical formula is the simplest whole number ratio of atoms present in given compound.

<h3>What is Molecular formula of Compound ?</h3>

Molecular Formula = Empirical Formula × n

n =  \frac{\text{Molar Mass}}{\text{Empirical Formula weight}}

Thus from the above conclusion we can say that Mass percentages of the the elements in the compound is the only additional information needed to calculate the empirical formula of a compound if the masses of each element of the compound are provided.

What volume of 15.7 M H2SO4 is required to prepare 12.0 L of 0.156 M sulfuric acid?
kirza4 [7]

The volume of 15.7 M H2SO4 is required to prepare 12.0 L of 0.156 M sulfuric acid is 0.12 L

<h3>Data obtained from the question</h3>

From the question given above, the following data were obtained:

  • Molarity of stock solution (M₁) = 15.7 M
  • Volume of diluted solution (V₂) = 12 L
  • Molarity of diluted solution (M₂) = 0.156 M
  • Volume of stock solution needed (V₁) = ?

<h3>How to determine the volume of the stock solution needed</h3>

The volume of the stock solution needed can be obtained by using the dilution formula as shown below:

M₁V₁ = M₂V₂

15.7 × V₁ = 0.156 × 12

15.7 × V₁ = 1.872

Divide both side by 15.7

V₁ = 1.872 / 15.7

V₁ = 0.12 L

Thus, the volume of the stock solution needed to prepare the solution is 0.12 L
